"Cause I'm on display, display, display," Melissa Gorga not-so-famously opined in her debut single on "The Real Housewives of New Jesey," but it looks like the aspiring singer has actually been connected to Hollywood for some time. The reality show star is actually the distant cousin of Ralph Macchio -- yes, the same Ralph Macchio of 1984's "Karate Kid" fame. Which would make the 50-year-old, Italian-American Macchio also the cousin-in-law of Melissa's sister-in-law Teresa Giudice… oh, well, you get it. In Jersey, it's somehow all relative anyway.

But Gorga also made it clear she wouldn't be inviting Macchio for dinner anytime soon. "We are like really distant cousins. Never even met him," Gorga told The Huffington Post. "We always said it when we were little. It's like through marriage, my aunt Rosile."

The TV actor ("Lost," "The Mentalist") has said about his famous "Mission Impossible" first cousin: "I never really worried about it. As I've amassed a body of work, the questions about Tom have gone away. I figured that if I did good work, I'd be seen for what I am."

Yes, they share the last name, but with McCarthy a fairly common surname it still came as a surprise when former Playboy Playmate Jenny tweeted at the hilarious "Bridesmaids" star: "Congrats to my cousin melissa mccarthy on her Emmy win!!"

Most recently, father and son appeared together in fellow Scandinavian Lars Van Trier's "Meloncholia."

The Barrymores need no introduction in Hollywood, but among the famous faces Drew Barrymore, now 36, can count among her upbringing is director Steven Spielberg, who, along with Sophia Loren, was deigned her Godparent. Steven Spielberg later went on to cast seven-year-old Drew in 1982's "E.T." The two remained close, with Drew pointing to the famed director as a constant stabilizing force in her publicly traumatic childhood. "He's been a very important mentor. He was the first stable male figure in my life. The best attribute a parent can have is consistency," she told Reader's Digest in 2009.

Twenty-two-year-old fashion model Daisy Lowe reportedly had no idea Bush singer Gavin Rossdale was her father until 2004, after a paternity test revealed that the rocker (and then-Godfather) was her biological parent. Though Rossdale initially refused to take the paternity test, it was later revealed that he and Daisy's mother Pearl had had a one-night stand. In the summer of 2011, Daisy appeared on the front cover of Playboy, in which she said of her father: "My whole life I thought my father was someone different... But Gavin and Gwen [Stefani] are really good people, and I value so much the time we get together."

Perhaps one of the best-known familial relations in the list, "Apocalypse Now" actor Martin Sheen's two sons Charlie Sheen and Emilio Estevez both went on to have successful careers in Hollywood, with one more vocally "winning" than the other. Estevez is the proper family surname; Martin adopted "Sheen" as his stage name, which Charlie then took on as well. The Hollywood connection doesn't stop there: Martin's younger brother Joe Estevez is also an actor.
